7 Claims.

7 This invention relates generally to an improvement in nurseryfurniture, and particularly the invention is directed to an improvedcrib or babybed. l

In cribs of the type now commonly in use, the mattress frameandconsequently the mattress, etc.-is immovable vertically and by reason ofthis fact and the depth of the crib, a person attending a child mustpick up the child from the crib and place the child on a higher table orthe like, in order to conveniently change the childs clothing or'otherwise administer thereto.

In order to avoid the'nec'essity of so transferring the child, Ipropose, as the principal object of this invention, to construct a cribso that the bed or mattress frame is adjustable from a normal loweredposition upward to a substantially raised position whereby when soraised, a person can easily and conveniently attend to the child withoutremoving the child from its. crib. Another object of the invention is toprovide a crib, as above, wherein the vertical movementwill fully appearby a perusal of the following specification and claims.

In the drawings similar .characters of reference indicate correspondingparts in the several views:

Figure l is a front elevation of the improved crib.

Figure 2 is a cross-section on line 2.2 of Fig.1, the mattress framebeing shown in .a fully lowered position.

Figure 3 is a longitudinal sectional elevation .on line 33 of Fig. 2,with the mattress frame lifted somewhat. 1

Figure 4 is a fragmentary longitudinal section on line 4--4 of Fig. 2.

Figure 5 is a fragmentary plan view of the foot pedal, shown inconnection with its holding ratchet.

Referring now more particularlyto the characters of reference on thedrawings, the improved crib includes, as usual, cover posts I which formthe legs of the crib; such posts being connected by side panels 2 andend panels 3 which extend from a plane somewhat belowthe bed level tothe upper ends of said legs.

A mattress frame is disposed in the crib and is normally disposed at bedlevel; such mattress frame comprising a rigid border frame 4 of reecarried by frame 4 and forms the mattress sup- I thenceextend intoenlarged vertical grooves or port. Whenin lowered or normal position,frame 4 rests on blocks or cross cleats 6 fixed on the end panels 3adjacent, but above the lower edges thereof.

At the ends and adjacent the corners, the frame 4V is provided withrigid .ears I which project through vertical slots 8 in the corner postsI, and

pockets 9 in said posts; said slots and grooves being of sufficientlength to allow of movement of the mattress from its lowered or normalposition upward to a position adjacent the top of the .crib.

The raising and lowering of the mattress frame is accomplished in thefollowing manner:

Aflexible cable I0 is connected at one end to each of the ears 1 withinthe corresponding groove 9, the cable extending upward over a pulley l Iin the upper end of said groove, and thence downward and about .a pulleyl2 in the lower end of said groove. From the corresponding pulley I2each cable passes through an opening l3 in the corner post, and thenextends longitudinally of the crib to substantially the middle thereof;the two opposed cables adjacent one side of the crib being secured inopposed winding relation o'na drum. l4 fixed on a horizontal transverseshaft !5, while the two opposed cables adjacent the other side of thecrib, are secured in opposed winding relation on. another drum l6likewise fixed on said shaft l5.

It will thus be seen that upon rotation of shaft IS in one direction,cables It] will wind onto drums l4 and I6, causing the mattress frame tomove upward relative to the remainder of the crib, while unwinding ofthe cables. from'the drum permits the mattress frame to lower of its ownweight.

"To manually rotate shaft 15, I provide a transverse lever ll disposedbelow shaft 15 and pivoted at one end on one side 2 of the crib; suchlever extending from said pivot across the crib and projecting below thelower edge of the other side 2', a foot pedal l8 being mounted on theprojecting' end of said lever. This lever is normally raised and anotherflexible cable I!) is fixed at one end on the lever at a point remotefrom its pivot, and extends upward and winds about, and is fixed at itsother end on, a third drum 26 on shaft IS. The cable I9 is so wound ondrum 20 that upon depression of pedal l8 and downward swinging movementof lever ll, cable H), as it runs off drum 20, rotates the latter in adirection to cause cables ID to wind onto drums l4 and I6 and to raisethe mattress frame.

Adjacent pedal l8, lever I! rides in a vertical slot 2| in a suitablymounted arcuate guide plate elements;

22; the portion' of the plate along one side of slot 2| being formed asa ratchet 23 having downwardly facing teeth, the lever being adapted forholding engagement with any one of said teeth. A leaf spring 24 is fixedon, lever IT and rides against plate 22 on the opposite side of the slotfrom ratchet 23; such spring urging lever l1 laterally into engagementwith said ratchf et. mattress frameis raised to the desired position,

and when lever I! is latched with. ratchet 23'; the mattress frameremains so raised. To low'er said frame, the pedal is shifted laterallyinter-directionto release lever I! from the ratchet, and they framereturns to a normal lowered position of its own weight, and at a speedcontrolled by foot pressure on the pedal. a

From the foregoi'ng'description it will be readlily seen that I haveproduced such a device as substantially fulfills the objects of l theinven ti'o'n'as set forth'here'in'. o I

While this specification sets forth in detail the Thus, as a persondepresses pedal l8, the

present'and preferred construction of the device, still in practiceisuchdeviations from such detail maybe resorted to as do not form a departure3 y from the spirit. of, the invention, as defined by the j appendedclaims;
